Hey all... After playing primarily jazz for the past 40 years I have been asked to join a jump blues/R&B/funk band and I need to upgrade my cabinet to add volume. I currently play thru a GK 400RB-IV into an Avatar 1x12/4ohm cabinet. Now I know I cannot add another 4ohm cabinet due to impedence problems. Would it be a good idea to consider replacing the 1x12 cabinet with 2 2x10 8ohm cabinets? I need to keep the weight down ( I am 63 years old and don't have a large vehicle). My thinking is I could use one of the 2x10 cabinets for the smaller jazz gigs I do and add the other to player the louder stuff. I have read all the past posts and kind of get lost in it all. I really appreciate your thoughts! Jim
